General Desc ription
The MAX4548/MAX4549 serial-interface, programmable,
triple 3x2 audio/video crosspoint switches are ideal for
multimedia applications. The devices include three
crosspoint switch matrices, each containing three inputs
and two outputs. To improve off-isolation, each switch
matrix has a shunt input and each output is selectively
programmable for clickless or regular-mode operation. A
selectable set of internal resistive voltage dividers sup-
plies DC bias for each output when using AC-coupled
inputs. To improve crosstalk, the voltage dividers include
four externally accessible bypass points.
The MAX4548/MAX4549 feature 35
max on-resis-
tance, 7
on-resistance matching between channels,
5
on-resistance flatness, and 0.07% total harmonic
distortion (THD). Additionally, they feature off-isolation
of -85dB at 20kHz and -72dB at 10MHz, with crosstalk
of -85dB at 20kHz and -55dB at 10MHz. The MAX4548
uses a 2-wire I
2
C -compatible serial interface, while
the MAX4549 uses a 3-wire SPI/QSPI/MICROWIRE-
compatible serial interface. These parts are available in
36-pin SSOP packages and are specified for the
extended (-40°C to +85°C) operating range.
